Sept. 25, 1934. M. G. CLARK HEATING SYSTEM FOR METAL BUILDING 'FiledApril 6, 1931 2 sheets-sneerh INVENTOR a number of angle irons 7immediately above and below the floor and secured therewith and with theribs 3 of the walls as by welding. 'Ihe floor is, therefore, in effectrigidly integral with the walls. The structure may of course have anynumber of floors, one being shown.

It will be apparent that the floor has a number of hollows 9 one betweeneach pair of webs 6, coextensive with the floor, and these hollows areopen-ended. Also the structure of the walls provides verticallyextending channels between the ribs 3 thereof, of which channels riserconduits 10 may be made by securing metal panel plates 8 over any pairof ribs 3 as by welding. As the hollows 9 open only at two sides of theoor, panel plates 8 are only useful to serve a floor at those sidesthereof. If the panel plates extend only above and below a iloor, thehollows 9 of'the latter will obviously be in communicating relation withthe risers 10 of the Walls. If a partition 1l be placed across one ofthe conduit risers at the top of a floor as inFig. 4, all flow betweenriser and hollow must be to or from below the floor. But if instead apanel plate 8 be laid above the floor the corresponding riser willextend thereabove as to serve another higher oor while stillcommunicating with the rst floor. Thus as indicated in Figs. 1 and 2. apair of closure members 12 are laid as indicated to provide manifoldsextending along below the floor at the edges adjacent the open ends ofthe hollows 9 thereof, A hot air furnace 13 has delivery connection asby the pipe 14 with one of these manifolds and return connection fromthe other by way of the pipe 15 and blower 16. There is communicationbetween the inlet manifold and all of the hollows 9 of the floor shownthroughout the entire length of the wall. As indicated Fig. 4,partitions 11 are placed between some of the ribs 3 of the correspondingwall just above the floor level so that ow is positively directed intothe floor. On other parts of the wall, however, instead plates 8 areemployed above the floor to form risers leading above the floor leveland to the next floor. On the opposite wall the arrangement is the same.

Thus aV continuous passage for the heating medium is supplied by thefurnace 13 across both floors in parallel relation, up one wall,through, and down the other wall therefrom, returning to the furnace byway of the blower.

To improve thermal efficiency, appearance, and acoustical properties themetal of the structure is covered with a non-metallic insulatingmaterial as indicated. Wall channel portions which are not used forheating conduits, are lled with this' material as at 17 in an amountsufficient that some of theyrnaterial overlies the plates 8 as at 18 topresent a smooth interior wall surface. A thickness of the material asat 19 is applied to the outside Wall surface, as `is a ceiling thicknessbeneath the floor indicated at 20. The floor is overlaid by a denser`material as at 21.

It will thus be apparent that a closed path is provided for the heatingmedium which path includes all of the floor areas and part of the wallareas. The conduit dimensions, therefore, while slight in one direction,are so extensive in the other that the sectional area for path of flowisample 4for all conditions. Moreover, no room space is taken up by anypart of the heating system. While air may be employed as the primarymedium of heat transfer, this air is recirculated in a closed path sothat impurities from the outside are not introduced into the insidethereby.

The arrangement described will be recognized as more or less elementary.In many instances as where heat is to be delivered through a single oor,it is desirable to provide a devious path through the oor. Anarrangement for this purpose is shown Figs. 5 and 6 wherein air isintroduced into one end of one of the end hollows of the oor as at 22and return connection is had at one end of the hollow at the oppositeend of the floor as at 23. The other ends of the hollows are closed bypartitions 24. Openings 2-5 are provided in the webs 6 of the floor. Theopenings may be located at opposite ends of alternate webs as indicatedin Fig. 5, so that the path of flow through the floor will be as shownby the arrows.

Frequently the building structure will include an inside wall 26 betweenoutside walls 27 as indicated in Figs. 7 and 8. Here it is preferablethat the heating risers be associated with the inside wall and thereturn risers with the outside Walls so that the direction of flow willbe as indicated by the arrows in Fig. 8. Fig. 9 shows a manner ofsupporting the inside wall which permits introduction of air theretoentirely therealong. 28 is a beam upon which the inside wall issupported, the wall having the rst adjacent floor level slightly abovethe eam. At one end of the w'all as at 29 the ribs 3 thereof are turnedto the right as appears in Fig. 9 so that by a short closure member 12aa path may be had from the manifold provided into the floor portiontoward the right. At the other end of the vwall as at 12b the ribs areturned in the other direction and the manifold 12b similarly providesfor introduction of heating air to the left-hand floor portion. 'I'hetwo floor portions have outlets at 30 and their webs 6 have openings 25so that flow through the floor portions will be as indicated by thearrows in Fig. 7 and the arrangement will provide a devious pathgenerally similar to that Figs. 5 and 6.

By the employment of panel plates 8 as directed in connection with Figs.1 and 2, provision may be made for heating additional overhead floors ina manner which will be apparent.

What I claim 15:.

Building construction of the class described comprising a sheet metalfloor panel, the panel comprising a plurality of sheet metal units ofcoextensive length assembled to provide a continuous repeated boxsection having spaced top and bottom faces with webs extendingtherebetween, a wall panel at the end of said floor panel and comprisinga sheet metal part secured with said floor panel and deformed to providevertically extending channels opening toward said floor panel and therecommunicating with cavities ofthe latter, said wall panel includingnonmetallic parts overlaid upon said sheet metal parts to close saidchannels on the corresponding side of said floor panel and therebyprovide conduit passage means effective to conduct a heating mediumbetween the hollows of said panels.
